+Oxford Semiconductor OXNAS SoC Family RESET Controller
+================================================
+
+Please also refer to reset.txt in this directory for common reset
+controller binding usage.
+
+Required properties:
+- compatible: Should be "oxsemi,ox810se-reset"
+- #reset-cells: 1, see below
+
+Parent node should have the following properties :
+- compatible: Should be "oxsemi,ox810se-sys-ctrl", "syscon", "simple-mfd"
+
+For OX810SE, the indices are :
+ - 0 : ARM
+ - 1 : COPRO
+ - 2 : Reserved
+ - 3 : Reserved
+ - 4 : USBHS
+ - 5 : USBHSPHY
+ - 6 : MAC
+ - 7 : PCI
+ - 8 : DMA
+ - 9 : DPE
+ - 10 : DDR
+ - 11 : SATA

+example:
+
+sys: sys-ctrl@000000 {
+	compatible = "oxsemi,ox810se-sys-ctrl", "syscon", "simple-mfd";
+	reg = <0x000000 0x100000>;
